Abstract

Digital video tape recorder apparatus comprises, at the recording side, a field store controlled by a programmable read-only memory to shuffle samples making up a digital television signal prior to recording, the shuffling alternating between a first and a second predetermined manner field by field of the television signal. At the reproducing side of the apparatus a reverse de-shuffling process is carried out.
